In plain terms
Great Britain's grid rules put any generator joining the network at 110,000 volts or more into their top class, Type D. A gigawatt ground receiving station would join at 275,000 or 400,000 volts, so it would be Type D.
The claim as recorded
Under the GB Grid Code (Issue 6 Revision 45, August 2026), a power generating module with its connection point at 110 kV or above is a Type D Power Generating Module whatever its size, and below 110 kV it is Type D from 50 MW; so a gigawatt-scale ground receiver connecting to the GB transmission system at 275 or 400 kV would fall in Type D, the top class of the code's A to D scale, rather than under any distribution-level standard such as IEEE 1547.
Scope and limits
This settles only the CLASS a GB station would be in. The Type D REQUIREMENTS (fault ride through, reactive power, frequency response) sit in the European Connection Conditions, which this update pack does not contain and which were NOT OBTAINED; the EU source regulation, (EU) 2016/631 (RfG), was NOT OBTAINED (EUR-Lex bot check), and IEEE 2800-2022 was not attempted. So OI-001's requirement reading stays open. Type D is the top of the A to D scale defined in the same Glossary; how demanding its requirements are is not stated here, because they were not read. 275 and 400 kV are the GB transmission voltages CLM-0798 names, not values from this source.
What it assumes
That a rectenna station counts as a Power Generating Module. The Glossary's Onshore Power Park Module covers non-synchronous units "connected through power electronic conversion technology" (PDF p.63), which a rectenna's DC-to-AC inverters are; the code does not name rectennas, and this reading is the drafter's.
Where it comes from
PDF p.92 (GD printed p.90), verbatim: "Type D Power Generating Module A Power Generating Module: (including an Electricity Storage Module): with a Grid Entry Point or User System Entry Point at, or greater than, 110 kV; or with a Grid Entry Point or User System Entry Point below 110 kV and with Maximum Capacity of 50 MW or greater." Same page, Type C is "below 110 kV and a Maximum Capacity of 10 MW or greater but less than 50 MW".
Basis: GB Grid Code definitions as in force at Issue 6 Revision 45
